Jack Kuenzle is an endurance athlete and coach for Uphill Athlete who travels around smashing some of the largest FKTs out there. In this episode we talk about many of his efforts, but we largely focus on his most recent FKT, a monstrous 26 hour record on the White Mountains 100. We also talk about his journey to endurance events, how to train to run in the mountains, and much more. Find Jack on Instagram @jackkuenzle.
